Modern wireless communication system often requires the antenna to work at several frequencies simultaneously. Multiband microstrip antenna has attracted much attention in modern wireless communication. This paper presents multiband compact pentagonal shaped antenna. A flexible design approach allows both dual band and triple band keeping the constant coaxial feed location and using the simple variation of radiating edge; the dual band and triple band operations are possible. Such antennas are implemented on RTduroid 5880 dielectric. All the simulations are carried out in IE3D software.
